Description of drawings
Fig. 1 is a kind of electricity bag of the utility model combination dust arrester structural representation;
Fig. 2 is electrostatic precipitator structural representation in a kind of electricity bag of the utility model combination dust arrester.
Among the figure, 1. housing, 2. air inlet, 3. gas outlet, 4. ash bucket, 5. air-purifying chamber, 6. blast pipe, 7. back-blowing device, 8. electrostatic precipitator, 9. sack cleaner, 10. battery lead plate, 11. connecting rods, 12. power connector ends.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
The utility model provides a kind of electricity bag combination dust arrester, as shown in Figure 1, comprise housing 1, end at housing 1 is provided with air inlet 2, housing 1 other end is provided with gas outlet 3, air inlet 2 is connected with housing 1 inside, gas outlet 3 and housing 1 enclose inside, housing 1 outside lower end is provided with some ash buckets 4, housing 1 outer upper ends is provided with some air-purifying chambers 5 near 3 places, gas outlet, each air-purifying chamber 5 top is connected to an end of L shaped blast pipe 6 by magnetic valve, and the other end of blast pipe 6 and gas outlet 3 UNICOMs are connected with back-blowing device 7 at blast pipe 6 near an end of gas outlets 3, housing 1 inner close air inlet 2 places are provided with electrostatic precipitator 8, electrostatic precipitator is connected with power supply, and housing 1 inner close 3 places, gas outlet are provided with sack cleaner 9, and sack cleaner 9 is connected with air-purifying chamber 5.
As shown in Figure 2, electrostatic precipitator 8 connects certain voltage by the battery lead plate 10 at storied placement, produce the high-voltage electrostatic field, when the dust grit in the flue gas passes through the high-voltage electrostatic field, and negative ions and electronics that battery lead plate is 10 bump and charged (or charged in the ion diffusion motion), grit with upper electronics and ion moves and long-pending being attached on the different in nature battery lead plate 10 at anisotropy battery lead plate under the effect of electric field force 10, make dust on the battery lead plate 10 fall into the ash bucket 4 of below by modes such as rappings, the flue gas by electrostatic precipitator 8 is purified.
Smoke dust by electrostatic precipitator 8 is not absorbed fully, flue gas from electrostatic precipitator 8 out after, enter inside from the outside of sack cleaner 9, by the filter bag filtration, dust is separated from air-flow, and the clean gas that has been cleaned enters air-purifying chamber 5 and discharges from filter bag inside.Dust is after filtration during bag filtration, the outer surface of staying filter bag forms the ash cake layer, when dust reaches certain thickness or certain hour, the deduster running resistance strengthens, need to clear up the dust on the filter bag, end in blast pipe 6 close gas outlets 3 is connected with a back-blowing device 7, the back-blowing device outside connects pressure-air, pressure-air oppositely enters air-purifying chamber 5 and finally enters filter bag inside by blast pipe 6, cause filter bag moment sharply to expand, because the acting in opposition of air-flow, make the long-pending dust releasing that is attached on the filter bag, after back-blowing device 7 was closed, filter bag bounced back again rapidly, formed a swollen contracting, the shake of filter bag harmomegathus, the long-pending dust that is attached to the filter bag outside comes off because of effect of inertia, and the dust that is fallen clearly falls into the ash bucket 4 of filter bag bottom, and back-blowing device 7 is by the PLC(Programmable Logic Controller) blowback frequency and blowback time of setting controls.
